NRF52 DK as central

[Alperen]

I use NRF52DK as central device I also use a SDK that is ble_app_uart_c code for my project. and i would like to take my peripheral devices whice are phone or PC their RSSI values but when i open my phone bluetooth and when i run my code. I don't see my phone's RSSI values on terminal. How can i solve that problem?. (Also my phone is  iPHONE6 that has bluetooh 4.2)

Not clear exactly what you're saying here - maybe a diagram would be clearer?

Alperen said:

So how are you collecting those values, and getting them to the terminal?

What debugging have you done to find where it's going wrong?

In nrf_ble_scan.c and in nrf_ble_scan_start()  function printf("%s",scan_evt.params.p_not_found->rssi); that i write to see my phone's RSSI value on the terminal.

So your nRF is a Central, and your phone is acting as a peripheral?

"my phone's RSSI" is a bit misleading.

"RSSI" stands for "Received Signal Strength Indication" - so saying "my phone's RSSI" suggests that you are talking about the level of signal received at your phone (ie, from your Central)

But the RSSI value returned in the nRF Central is the level of signal received at that Central.

Yes, it's true. But I don't see my phone RSSI. I will use a peripheral which is a beacon and try again. Probably, I'll solve my problem. Thank you. I don't think problem about my code. I guess, I can have a hardware problem.

Sorry, I was saying that i don't see the RSSI value returned in the nRF Central for my phone when i use it as a peripheral . I see NULL. It's my problem .YES.

Sorry, still confused.

Perhaps a diagram would help?

Or does this answer the question: https://devzone.nordicsemi.com/f/nordic-q-a/71831/returned-rssi-value/295518#295518 ?

I solved my problem, thank you!

For the benefit of future readers, could you describe what was the problem, and how you solved it.

Then mark that as the solution:
